I guess it is based on the Clinton time frame when steel core 7.62x39 was stopped for imporation... the rumor being that it was due to oly's plans to build oa93 in that caliber. I even heard the reason no top tier builders were building 74 pistols was because they didn't want this to happen since then 74 would be considerd a hand gun round and put on the bad list of ammo.

Super nice build Will. A+..
Pirate turned me on too Aims .11 cents a round ammo.
I had too send them in proof of being 21 before they would sell the ammo too me.
Told the lady when I was 21, our wonderful Government was giving me any type of explosive device and implements of killing I needed.
Even gave me a full auto without a tax stamp.
Plus all the free ammo I wanted. She still wanted proof of age.
Wonder if I joined the reserves, I could travel with the troops in a hum-around, if they would let me have free ammo and a full auto. I could mount the machine gun on my hummer.
I am saving my pennies for one of your silencers. Probably will have too have ProjectGuns do the transfer.
